Marvel has big plans for the lucky fans in Hall H today. Their Comic-Con presentation is easily one of the most anticipated of the entire show, and with good reason — a billion and a half dollars worth of reason, in fact.

On "Guardians," he said: "That would be Marvel in space. That's a great concept and a great idea, and potentially one of our films in the future."

As for "Black Panther," he noted that T'Challa "has a lot of the same characteristics of a Captain America: great character, good values." But the movie might be difficult to pull off, he said, because of having to create Wakanda from the ground up. "It's always easier basing it here. For instance, 'Iron Man 3' is rooted right here in Los Angeles and New York. When you bring in other worlds, you're always faced with those difficulties."

No matter what movie they wind up going with, D'Esposito emphasized the importance of exploring characters beyond the core heroes of "The Avengers."

"It can always be an 'Iron Man,' 'Thor' and 'Cap,'" he said. "We need to grow from there."

He added that there's a temptation to try putting out three Marvel movies a year in the future, as opposed to the current model of two movies a year.

"The temptation is to try a third, and maybe we will," he said. "But we're a small group. It's very, very difficult. We're unique as a studio. We're not just the studio, we produce the films ourselves. It requires a lot of hands on time and effort. You can only stretch it so much before it breaks. So we're very mindful of that. We have to check our enthusiasm. We can't be overly aggressive. We still want to make quality films, and that's the most important thing for us."
